SPECIFICATION forming part of Letters Patent No. 772,864, dated OCtoberlS, 1904.

Application filed December l, 1903. Serial No. 183,419. (No model.)

' T0 1J/Z whom, t may concern:

Be it known that I, ARTHUR H. BRANDON, a citizen of the United States. residing at Pem- .berville, in the county of Wood and State of Ohio, have invented certain new and useful Im- '..provements in Fishing-Tools; and I do hereby declare the following to be a full, clear, and eX- My invention relates to improvements in .fishing-tools for engaging and withdrawing broken or disabled valves from oil or other wells, and hasparticular reference to improvements in the invention for which application for Letters Patent was tiled by me on October 3, 1903, being Serial No. 175,565.

In the employment of the means heretofore devised for the recovery of broken or disabled valves from wells it has been necessary to first withdraw the sucker-rod, which is usually several hundred feet long,- from the well, remove the sucker-valve from the lower end thereof, secure the fishing-tool in its place, and then relower the sucker-rod with the fishing-tool attached into the well for the purpose of engaging and withdrawing the valve.

The object of my present invention is to obviate the necessity for the several steps enumerated by providing simple and eiiicient means whereby the fishing-tool is adapted to be suspended at all times from the lower end of the sucker-valve and to remain in the well therewith in inoperative position during the pumping operation and Awhen desired to be released from its inoperative position,so as to adapt it to engage the valve to be withdrawn, thus obviating the necessity of withdrawing the suckerrod from the well and removing lthe suckervalve in order to enable theishing-tool to be secured to said rod preparatory to recovering the disabled valve.

The invention is fully described and finally claimed inthe following specification, of which the accompanying drawings form a part, in which- Figure l is a verticalsectional viewn of the casing of a well, showing the usual sucker-rod and sucker-valve suspended therein, the inletvalve in position below the same, and my invention in vertical longitudinal section suspended in inoperative position from the lower end of the sucker-valve. Fig. 2 is a similar view except that the sucker rod and valve are not shown, showing my fishing-tool in operative position and in engagement with the lower valve. Fig. 3 is a cross-sectional view of the tool-carrying member, taken on the dotted line a .fc in Fig. 2; and Figs. 4 and 5 show a modification vof the locking mechanism employed for retaining the fishing-tool in elevated position within its casing while being lowered into a well.

Referring to the drawings, A represents a sucker pipe or casing which has the inlet-valve B at its lower end and the sucker-rod C and sucker-valve D suspended therein, the said casing having its upper end threaded to a feedpipe E of slightly-greater diameter than said casing, all of which are common to the class' of wells in which my invention is adapted to be used.

My invention is shown in the drawings as comprising the elongated cylindrical member 1, which is made'of suitable diameter to fit and reciprocate freely within the sucker-casing A and has its upper end internally threaded at 2 to engage the lower threaded end of the sucker-valve D, as shown in Fig. l. The said cylindrical member l is adapted to form a housing for the engaging tool 3,

which -forms the subject of my said former api plication, the same comprising the enlarged portion, the longitudinally-slotted portion 5, having the annular flange or shoulder 5l at its free end, and the expanding tongue 6, the said tongue being adapted to normally extend below and have a limited longitudinal movement within the slotted portion I5`of said tool, as shown in Figs. l and 2. I do not coniine myself, however, tothis particular form of tool, as any suitable grappling means may be employed in connection with my invention.

The tool 3 is retained in different positions with relation to the member l by means of the locking-block 7, which rests and is transversely movable within a suitable opening provided through the casing of said member TOO and has its upper inner edge beveled, the annular internal shoulder 8, which is adapted to coact with the enlarged portion 4 of said tool, and the transversely-movable pin 9, which is mounted in the lower portion of the casing l and adapted when in extended position to engage with the lower end of said tool and retain the same entirely` inclosed within said member, as shown in Fig. 1. The sliding key 10 has a limited longitudinal movement within the dovetailed groove 10, provided in the side of the casing l, by reason of the stop-pin 1l operating in the groove 11, and the movement of the pin 9 is controlled by the location of the key 10, which is provided with a notch 12 for receiving the end of said pin 9 when said key is in the elevated position shown in Fig. 2, thus unlocking and releasing the tool 3 from the position shown in Fig. l.

The outer surface of the memberl is pro- Vid ed with a series of longitudinal grooves 13, which terminate at their upper ends in the apertures 14, which lead to the interior of the member l and are in communication with the opening through the sucker-valve D, thus forming ways for the passage of oil or other iuid past the member l during the pumping operation should said member fit snugly in the casing A.

In the operation of my invention the member l is secured to the lower end of the suckervalve D and lowered in the well therewith, the tool 3 being retained entirely within the same by reason of the locking-pin 9 engaging the lower end of said member, said pin being held in such position by the key lO, as shown in Fig. 1. This position of the tool 3 is maintained until the sucker-valve D and member l are lowered to the bottom of the sucker-casing A, when the extended key lO strikes the casing` of the lower valve B and is forced up thereby, thus unlocking the pin 9 and permitting the tool 3 to drop within the member l until the enlarged portion 4 thereof comes in contact with the extended beveled edge of the lockingblock 7. The pump is operated with the tool 3 suspended in this position until it is desired to withdraw the valve B, which is accomplished by first lifting the member 1,by means of the sucker-rod C, until the locking-block 7 comes within the enlarged portion E of the pipe casing, when it is forced out by the weight of the tool 3 against the beveled edge thereof, thus allowing said tool to drop until its enlarged portion L engages the shoulder S, as shown in Fig. 2. The tool 3, which is now in position to adapt it to engage with the valve B, is relowered into the casing A, the block 7 being again forced in and loc-king the tool against an independent upward movement. The tool is thus lowered until the extended tongue 6 passes through the opening in the lower valve-easing and strikes the ball therein, thus forcing said tongue up and expandmg the flanged portion of said tool, so as to i engage the valve and enable it to be withdrawn.

lt will be apparent that the locking-pin 9 or other suitable means is necessary in order to retain the tool 3 in inclosed position within the member l until the locking-block 7 has passed within the smaller casing A, after which time and during the pumping operation said tool is retained in inelosed position within said member by reason of the enlarged portion 4 thereof engaging the beveled edge of said block.

A modification of the means employed for retaining the engaging tool in inclosed position within its casing while it is heilig' lowered into a well is shown in Figs. 4C and 5 of the drawings, i n which a represents the suckerpipe, the enlarged portion of the pipe-casing, and c the cylindrical member for carrying the fishing-tool f/. In this construction the locking-block (l is adapted to be held in engagement with the enlarged portion of the fishing-tool f/ during the lowering owration by means of the split s])ring-ring` 1. As the member e is lowered and enters the smaller casing fi the ring a engages the upper edge thereof, as shown, and is caused to remain stationary until the member c has been lowered sufiiciently for it to spring within the periliherial groove or seatj", provided in said member for its reception, and thus be released from engagement with the edge of said casing.

It is obvious that such changes in the form,

proportion, and minor details of construction of the parts as fairly fall within the scope el' my invention may be made without departing from the spirit or sacrilicing any of the advantages thereof.
